Question

我正在尝试使用Creof包及其Distance函数。当我执行以下代码时，我得到以下异常：

public function getMapDecorator(array $requestInformation, $type) : MapDecorator {
        $queryBuilder = $this->entityManager->getRepository('AppBundle:Provider')->createQueryBuilder('provider');

    $point = new Point(0,0);
    $point->setLongitude($requestInformation["currentLongitude"]);
    $point->setLatitude($requestInformation["currentLatitude"]);

    // build the query
    $queryBuilder
        ->select('provider, DISTANCE(:point, provider.coordinates) AS HIDDEN distance')
        ->having('distance <= :radius')
        ->where("provider.type = :type")
        ->setParameter('type', $type)
        ->setParameter('radius', 10)
        ->setParameter('point', $point)
        ->orderBy('distance')
    ;

    $providers = $queryBuilder->getQuery()->getResult();

    return null;
}

执行此操作时，这是我得到的错误

“执行'SELECT a0_.id AS id_0时发生异常， a0_.type AS type_1，AsBinary（a0_.coordinates）AS coordinates_2，距离（？，a0_.coordinates）AS sclr_3，a0_.path_id AS path_id_4， a0_.coordinate_id AS coordinate_id_5 FROM provider a0_ WHERE a0_.type =？有sclr_3＆lt; =？ ORDER BY sclr_3 ASC'with params [{}，\“professional \”，10]：\ n \ n \ nSQLSTATE [42000]：语法错误或访问违规：1305功能mydbname.Distance不存在“

我想知道为什么我收到此错误，我可以看到调用此文件的调试：CrEOF\Spatial\ORM\Query\AST\Functions\MySql\Distance

我的配置中也有以下内容：

好的发现了这个问题。 Mysql不赞成使用Distance函数来支持ST_Distance。这个包应该更新，但目前我在我的包中创建了以下类：

namespace AppBundle\ORM;

use CrEOF\Spatial\ORM\Query\AST\Functions\AbstractSpatialDQLFunction;

/**
 * Distance DQL function
 *
 * @author  luca capra <luca.capra@create-net.org>
 * @license http://dlambert.mit-license.org MIT
 */
class STDistance extends AbstractSpatialDQLFunction {

    protected $platforms = array('mysql');
    protected $functionName = 'ST_Distance';
    protected $minGeomExpr = 2;
    protected $maxGeomExpr = 2;

}

我在配置中添加了

st_distance:            AppBundle\ORM\STDistance

我现在使用ST_Distance代替Distance

Symfony Creof功能mydbname.distance不存在
